METALLIC COLUMN.

SPECIFICATION forming part of Letters Patent No. 492,518, dated February28, 1893.

Application filed May 6, 1892. Serial No. 431,978. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM C. GHoLsoN, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State of Ohio,have invented certain new and use ful Improvements in Metallic Columns,of which the following is a specification, reference being had to theaccompanying drawings.

The object of my invention, and the advantages arising therefrom will beapparent from the detailed description hereinaftercontained.

In the accompanying drawings:Figure 1, is a side elevation of a metalliccolumn constructed according to and embodying my invention. Fig. 2, is atransverse section taken through the column shown in Fig. 1. Fig. 3 is aView similar to Fig. 2, excepting that bracket washers are used in theformer to adjust the space between the angle-irons. Fig. 4C, is aperspective View, on an enlarged scale, of the washer shown in Fig. 3.Fig. 5, is a central longitudinal section through the top portion of myimproved column, the latter being provided with a metallic cap securedthereto.

My improved metallic column consists, preferably, of four strips ofangle-iron A connected together by means of stay-bolts B, as shown, toform a square or rectangular column in cross-section. The strips ofangle-iron are placed in position, a portion of their edges restingagainst the stay-bolts, as more clearly shown in Fig. 1,the diameter ofsaid bolts regulating the size of spaces a between adjacent i'aces ofsaid angle-irons. After having placed the angle-irons to position in themanner aforestated, the nuts b are then screwed onto one end of thestay-bolts. The staybolts are preferably provided with suitable washersd, the latter resting against the outer face of the angle-irons, asshown in Figs. 1 and 2: but, said washers might be dispensed with, inwhich event the head of each bolt and its nut will bear and impingeagainst the outer face of said angle-irons, at each side of the spacesa. The nuts 1) are preferably tightened simultaneously, in order thatthe angle-irons may be brought securely and evenly together.

hen desired that the spaces a, between adjacent strips of angle-iron, beof a width greater than the diameter of the stay-bolts, I have provideda washer E with inwardly projecting ribs 6, said ribs being located, asshown, at each side of the bolt-opening. These ribs may be cast anydesired distance apart to accommodate the spaces a required. When placedin position, the edge portion of each an gle-iron rests against theouter face of each rib e,the bolts passing through the opening in eachwasher between its ribs, as shown in Fig. 3.

By the use of washers such as shown in Fig. 3, a column may be increasedin size without additional material and without increasing the size orweight of the angle-irons.

My improved metallic column may be used for a variety of purposes, and Ido not limit my invention to any particular purpose or use.

In Fig. 5, I have illustrated my improved metallic column as beingapplicable for use as a fence-post; and, when so used, it is desirablethat the same have a suitable cap or cover. This cap or cover, aspreferably constructed, consists of four plates F, the top portions ofwhich decrease in size and are adapted to meet at a common center. Theseplates are secured to the outside faces of the column by means ofstay-bolts B, similar to those already described,said bolts also servingto connect and combine the angle-irons A.

The advantages of my invention are many and apparent. The angle-ironsare readily formed, after which the column may be constructed withoutboring or drilling. The angle-irons may be shipped in a crated orcompact form; and, after having arrived at their destination, saidangle-irons may then be placed and secured together in the manneraforestated to form columns. Said columns are readily and quicklyformed,the services of a skilled mechanic not being required. The ribbedwashers E are also of very great advantage. The ribs 6 may be formedthereon varying distances apart; and, in this manner varying dimensionsof columns may be formed from one uniform size of angle-iron.

What I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a rectangular metallic columnconsisting of four strips of angle-iron connected together by means ofstay bolts passed transversely the edges of said angle-irons impinge,substantially as set forth.

4:. A metallic column consisting of strips of angle-iron connectedtogether by stay-bolts as set forth, the top of said column beingprovided with cap-plates, said plates being connected thereto by thesame stay-bolts which retain the top portion of the angle-irons inplace, as set forth.
